Abstract

The invention relates to a visual-servo-based screw hole locating and screw locking-removing method. A screw hole is located and a screw is locked and removed through a visual-servo-based screw hole locating and screw locking-removing device. The position information and pose information of the target screw hole or screw are obtained through a visual measuring module of the visual-servo-based screw hole locating and screw locking-removing device. Screw hole locating and screw locking and removing are controlled to be performed through a control performing module of the visual-servo-based screwhole locating and screw locking-removing device. Through the visual-servo-based screw hole locating and screw locking-removing method, locating precision of the screw can be improved to a large extent. A mechanical arm is used as a moving carrier, the work range is increased, and locking and removing work of the screw can also be conducted in an environment to which a worker cannot go conveniently. A point-to-surface screw or screw hole locating method is provided.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to a method for positioning screw holes and locking and removing screws based on visual servoing. Background technique [0002] In the process of mechanical equipment manufacturing, each component needs to be assembled, and the assembly process directly affects the efficiency of equipment manufacturing, and mounting screws is the most basic assembly process. The efficiency of screw assembly directly affects the efficiency of manufacturing. In addition, electronic products are now developing at a rapid pace, and the demand is also increasing, so mass production must be realized. On the assembly line of electronic products, there are also a lot of screws to be locked and unloaded. Some working environments are small in space, or there are strong magnetism, strong electricity and other working conditions that are not suitable for the staff, which will affect the efficiency...
